| 摘 要：以丙烯酸(AA)和丙烯酰胺(AM)為原料,過(guò)硫酸鉀為引發(fā)劑,N,N-亞甲基雙丙烯酰胺為交聯(lián)劑,采用水溶液聚合對丙烯酸-丙烯酸胺(PAAAM)高吸水樹(shù)脂的合成條件進(jìn)行了優(yōu)化。結果表明,在室溫下最大吸蒸餾水倍率為2710g/g,在w(NaCl)=0.9%的水溶液中吸水倍率為133g/g�？疾炝藛误w質(zhì)量分數、交聯(lián)劑質(zhì)量分數以及引發(fā)劑質(zhì)量分數對PAAAM在蒸餾水及w(NaCl)=0.9%溶液中吸液性能的影響,并對實(shí)驗結果進(jìn)行了回歸分析。 |

| Abstract：Some superabsorbents(PAAAM)were prepared from copolymer of part-neutralized acrylic acid(AA)and acrylamide(AM) with potassium peroxydisulfate as initiator,N,N'-methylene-bis-acrylamide as crosslinking agent,by means of water solution polymerization.The polymerization conditions were optimized by orthogonal experiment method and single factor experiment method,and the absorbencies of PAAAM in distilled water and 0.9% NaCl solutions were regression-analyzed.The maximum absorbency of the superabsorbent in dist... |
